摘要

本文利用FM-CW制式的陆基微波散射计对裸土进行了后向散射系数的测量

利用IEM模型对土壤的湿度及表面粗糙度进行了反演

并将反演结果与实地测量结果进行了比较研究.研究表明

通过多角度微波后向散射测量可以较为准确的确定表层土壤的湿度

而用光学方法进行的地表粗糙度的实地测量结果与反演结果相差较大

反映了微波频段的电磁波对地表具有的穿透作用.文中还对测量中存在的误差进行了较为详细的分析.

Abstract

A FM-CW ground base C-band scatterometer is used to measure the bare soil surface.The measurement was conducted at different incident angles and for two soil moisture conditions.In-situ measurement is also arranged simultaneously in order to verify the retrieved moisture.During the moisture retrieval

the integration equation method (IEM) is used.The results show that the method could be used to build up the soil moisture database and could then be used for satellite data applications.
